SPRING BED-BOTTOM.

SPECIFICATION forming part `of Letters Patent No. 275,928, dated April 1'7. 1883.

Application filed September 11,1882. (No model.)

I in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a sectional side elevation of my improvement. Fig. 2 is a plan view of the same with a hanger in sectioin Fig. 3 is a plan view of the bed-bottom folded. Fig. 4 is an end elevation of the same.

The object ot' this invention is to facilitate the folding of spring bed-bottoms and promote convenience in storing and transporting the same. f l

The invention consists in a spring bed-bottom constructed with lower and upper crossslats held apart by interposed springs. Upon the upper cross-slats are laid the upper longitudinal slats, which are kept in place by rivets and by rods passing through the slats and springs. The lower cross-slats are kept in place by longitudinal slats connected with them near their ends. rIhe upper longitudinal slats, at the sides of the bed-bottom, are slotted longitudinally, so that they can be pushed back to lessen the length of the bedbottom when folded. The bed-bottom is supported by adjustable hangers, which are provided with dovetailed slots to receive and hold the ends of the lower cross-slats, and serve as guides to the ends of the upper cross-slats, as will be hereinafter fully described.

A represents the end boards, and B the side rails, of a bedstead.

To each side rail, B, are attached three or more hangers, C, which are slotted from their in the hangers G, to receive the fastening screws, so that they can be readily raised and lowered to support the bed-bottom in ahigher or lower position, as may be desired.

Upon the upper cross-slats, E, are laid seven or other desired odd number of longitudinal slats F, the second, fourth, and sixth of which are secured to the said cross-slats E by loose rivets G, that will allow the said longitudinal slats to turn upon the said cross-slats. The first, third, fth, and seventh longitudinal slats F are secured in place by short rods H, which pass through the said slats F and through the upper cross-slats, E, and thelower cross-slats, D, and upon which, between the cross-slats E D, are placed spiral springs I.

The rods H of the side slats F also pass` through the longitudinal slats J, placed beneath the lower cross-slats, D,and which serve to keep the various parts of the bed-bottom in their proper relative positions when the said bed-bottom is being handled.

V Upon thelower sides ofthe first, third,ifth, and seventh slats F are formed, or to them are attached, rounded projections K, which, when the bed-bottom is folded, strike against the edges of the other slats F and cause the slats to which they are attached to rise, so that the longitudinal slats will overlap each other, and thus allow the bed-bottom tobe folded more compactly than would otherwise be possible. j

In the side slats F, but upon the opposite sides of the rods H, are formed longitudinal slots L, and in the slats F, next to the said side slats, are formed longitudinal slots M, of

half the length ofthe slots L, so that when the bed-bottom has been folded the side slats can be pushed back to prevent their ends from projecting beyond the ends of the cross-bars E andthe third slats F, as shown in Fig. 3.

To the lower side of one of the lower cross- Jbars, D, is pivoted the end of a catch-bar, N,

IOO

stantially as herein shown and described, and 3. In a spring bed-bottom, the side longiconsisting of the lower cross-slats, D, the upper cross-slats, E, the upper longitudinal sluts F the lower longitudinal sluts, J, the rivets Gr, the rods H, and the spiralvsprings l, as set' forth. Y

2. In a spring bed-bottorn, the combination, with the cross-slats D E, the lower longitudinal slats, J, the rivets G, the rods I-I, and the springs I, of the upper longitudinal slats F, provided with rounded projections K, substantially as herein shownand described, whereby the upper longitudinal sluts willbeoverlapped, when the bed-bottom is folded, to cause the said bed-bottom to fold coinpactlusset forth.

tudinal slats F, having longitudinal slots L' M formed in them, substantially as herein shown and described, whereby the said side slats can be pushed back to lessen the length of the bedbottom when folded, as set forth.

4. In a spring'bed-bottom, the adjustable hangers C, provided with dovetniled slots to receive and hold the dovetailed ends of the lower cross-slats, and to serve as guides to the upper cross-slats, as set forth.
